Notes.
Only a few published papers have provided detailed descriptions of the female terminalia in
Gyponini
:
Engel & Takiya (2012)
,
Da-Silva
et al.
(2014)
,
Domahovski
et al
. (2014
, 2015),
Da-Silva & Coelho (2015)
, and Domahovski & Cavichioli (2015, 2017a, b). The difficulty of associating males and females and the apparently low morphological variation in the structures of the female terminalia are among the possible reasons for the small number of studies on this subject.
Da-Silva & Coelho (2015)
described the female terminalia of
Polana
(
Polanana
)
amapaensis
Coelho, 1991
and
Domahovski & Cavichioli (2017a)
described those of three species of
Polana
(
Varpulana
):

naja
Domahovski & Cavichioli, 2017
, and
P

sapitanduva
Domahovski & Cavichioli, 2017
. The structures of the female terminalia of all these species have characteristics similar to those of
P
. (
S
.)
desela
, which are not known to occur in other genera of the tribe. These include: (1) first valvula with basal portion produced anterad and rounded (
Fig. 34
); (2) first valvula with apical portion with lateral carina bearing small teeth (
Fig. 36
); and (3) second valvula with ventral margin expanded, forming flap (
Fig. 38
). However,
P
. (
S
.)
desela
differs from the aforementioned species in having the second valvula with the apical fourth narrowed and the dorsal margin without teeth (
Figs 38, 39
).
